Op Amp Rail Splitter Question

[graygem]

I have a circuit with 2 TL074 quad op amps. I'm using 1 of the Amps on the first TL074 as a rail splitter for the other 3 on the same TL074. I need a rail splitter for 3 of the amps on the 2nd TL074. My question is, can I use the one rail splitter, of do I need to use 2 separate splitters? The forth amp on the 2nd TL074 is already being used but doesn't need the half voltage. If I can, what is the best values to use for the splitter's resistors and capacitor?

Thanks for any help.

if you can have just one "gnd" from one rail splitter in the circuit it will reduce some possible error sources

you do have to check the current into the gnd against the op amp output spec
